Question

What is the most important constituent of Polymerase Chain Reaction?

• A. DNA polymerase
• B. DNA primers
• C. DNA Sequence
• D. All the above components

Answer 1

The correct option is B DNA primers

While every component of the PCR mix is important for the amplification to be successful, DNA primers hold the key in this method. The correct complementary primers are needed for the DNA polymerase to attach to the DNA sequence and start the replication process.
